Feline Panleukopenia: Welfare and Prevention
Disease Overview
Feline panleukopenia virus (FPV) is a parvovirus causing haemorrhagic gastroenteritis and bone marrow suppression in cats. It is closely related to canine parvovirus. Kittens and unvaccinated cats are most susceptible. The virus is highly stable in the environment (survives for months to years on surfaces). Intrauterine infection causes cerebellar hypoplasia in kittens born to infected queens.
Welfare Consequences
FPV causes severe suffering: profuse vomiting, bloody diarrhoea, profound lethargy, hypothermia, and abdominal pain. Severe leucopenia leaves cats defenceless against secondary infection. Mortality in untreated cases is high (50-90% in kittens). Survivors of cerebellar hypoplasia have permanent neurological deficits (ataxia, tremors, intention tremor) but, with appropriate care, can have an acceptable quality of life.
Diagnosis and Treatment
Rapid diagnosis using parvovirus antigen tests is critical. Treatment is intensive supportive care: intravenous fluids, anti-emetics, antibiotics for secondary infection, nutritional support, and warmth. Blood or plasma transfusions support cats with severe anaemia or hypoproteinaemia. Strict isolation and environmental decontamination (sodium hypochlorite) prevent spread.
Prevention Through Vaccination
Core vaccines against FPV (typically combined FHV-1/FCV/FPV, the 'tricat' vaccine) provide excellent protection. Kittens should receive a primary course starting at 8-9 weeks, repeated at 12 weeks. Boosters are given at 1 year and then triennial for FPV in adults (immunity is long-lasting). Rescue centres and multi-cat households must maintain rigorous vaccination programmes. Vaccination of queens before breeding prevents intrauterine infection.
Shelter and Rescue Welfare
Rescue environments are high-risk for FPV outbreaks due to frequent intake of unvaccinated animals. Intake vaccination (including in-shelter use of intranasal vaccines for rapid protection), isolation protocols for new arrivals, and rigorous disinfection are essential. An outbreak in a rescue shelter is a major welfare emergency requiring immediate isolation, treatment, and environmental decontamination.
